You can create a virtual interface, which has a single physical interface. This function enables failover because of a line failure even on a cluster system that has only one physical interface available for use.
Figure 2.28 Single physical interface configuration shows an example of single physical interface configuration.

Note
This feature is capable for all switching modes.
The selection criteria of a mode where a single physical interface is used on GLS relies on the mode where redundant line is used. Refer to the fault monitoring function requirements section on "1.1.1 Functional comparison" before selecting a single physical interface for either mode.
